Turning on input event printing[1], when using Ctrl+Alt+F1 switching
away from unity8, I see a continuous stream of input events being sent
from Mir to Unity8, while on VT1:
[2017-03-23:12:36:53.419] qtmir.mir.input: Received
MirKeyboardEvent(action=repeat,key_code=0x1008ff2b). Dispatching to
ShellView(0x558b6b947ea0)

and actually, switching back to Unity8's VT, the key repeat events don't stop!
Adding Mir to the bug
[1] qdbus com.canonical.Unity8 /com/canonical/Unity8/Debugging
com.canonical.Unity8.Debugging.SetLoggingFilterRules "qtmir.mir.input=true"
** Also affects: mir (Ubuntu)
Importance: Undecided
Status: New
** Summary changed:
- Unity8 spins for a long time after being on an inactive vt
+ Mir sending key repeat events continually to nested shell after VT switch
(causes Unity8 lockup for a while)
** Changed in: unity8 (Ubuntu)
Status: Triaged => Invalid
